浙江湿地类型变化局地温室效应遥感评估
摘要
Abstract
The wetland ecosystem,known as the"kidney of the earth",is a key carbon sink storage site on the earth and plays an important role in climate regulation.However,it is now facing the problem of reduced wetland area and functional degradation.Changes in wetlands have further led to an increase in greenhouse gas emissions and intensified the local greenhouse effect.Taking Zhejiang Province as the study area,Landsat OLI and OLI-2 series images were used to conduct wetland supervision and classification,extract wetland type change results,and quantitatively evaluate the emission characteristics and changes of major greenhouse gases(including methane,carbon dioxide and nitrous oxide)during the evolution of wetland ecosystems.It was found that after natural wetlands were transformed into artificial wetlands,their carbon sequestration capacity significantly decreased and greenhouse gas emissions increased.The results show that changes in wetland types are closely related to greenhouse gas emissions,which in turn leads to an enhancement of the local greenhouse effect,which in turn further affects climate change.The findings of this study provide certain scientific basis for wetland protection,land use planning and greenhouse gas emission control.关键词
